Honestly I think adding this would be cool but it would be relatively pointless. Most of the time, if ts want a quick kill, they'll aim for the head and get it over with. I think whether they know the health of a player or not the head shot will still be the most logical choice. Meaning seeing a players health wont really help. When things start to get hectic, I doubt players will think to look at the hp of players rather than just gun them down. I think this would be a cool feature but one that doesn't need to be added and one that won't make too much of an impact. Also, from the perspective of the innos and detectives. It would be nice to see a lower hp player and instantly be sus of them but I think this change would do little to affect the game from their point of view. From my experience only try hards listen to people calling out high sus and even then its not that many players.
